2-trichloroethyl) phosphate] triesters and 5'-phenyl phosphoramidate derivatives which, acting as membrane soluble prodrugs, could release the free phosphate form inside the cell. The 5'-(phenylmethoxy)alaninyl phosphate derived from 8-aza-isoddA was found active against HIV-1 and HIV-2 with a potency similar to that of isoddA, while the anti-HIV potency of 5'-(phenylmethoxy)alaninyl phosphate of isoddA proved
抗HIV剂2',3'-dideoxy-3'-oxoadenosine(isoddA)的某些aza和deaza类似物(8-aza-,8-aza-1-deaza,8-aza-3-deaza-,1 -deaza-和3-deaza-isoddA)已合成,并且在体外对HIV没有活性。通过合成一系列5'-[磷酸双(2,2,2-三氯乙基)]三酯和5'-苯基来检验这些异核苷无活性可能是由于它们对细胞核苷激酶亲和力较弱的假设。可用作膜可溶前药的氨基磷酸酯衍生物可以释放细胞内的游离磷酸盐形式。发现源自8-氮杂-isoddA的5'-(苯基甲氧基)丙氨酰磷酸对HIV-1和HIV-2有活性,其功效与isoddA相似,而抗HIV的功效为5' 证明isoddA的-(苯基甲氧基)丙氨酸磷酸酯显着高于isoddA的磷酸,特别是针对HIV-2,与AZT相似。进一步的证据表明,通过合成其5'-三磷酸衍生物可以得到8-aza-i
